We divide 644900 by 47
We want to divide 644900 by 47.

Going ahead to step 1:
If we divide 6 by 47, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 47

Let's proceed to step 2:
47 goes into 64 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 47 from 64 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 47

Going ahead to step 3:
174 divided by 47 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 141 from 174, we get 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 47

Moving on to step 4:
When dividing 339 by 47, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Subtract 329 from 339 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 47

On to step 5:
47 goes into 100 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1372.0
Deduct 94 from 100 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 47

Moving on to step 6:
60 divided by 47 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 13721.0
Subtracting 47 from 60 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
47 goes into 130 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 13721.2
Deduct 94 from 130 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 47, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 13721.27
The remainder is 31 after subtracting 329 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
47 goes into 310 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 13721.276
Deduct 282 from 310 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
47 goes into 280 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 13721.2765
If we subtract 235 from 280, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
If we divide 450 by 47, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 13721.27659
The remainder is 27 after subtracting 423 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
47 goes into 270 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13721.276595
Subtracting 235 from 270 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
47 goes into 350 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 13721.2765957
If we subtract 329 from 350, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
47 can be fit into 210 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 13721.27659574
Deduct 188 from 210 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 13721.27659574, with a leftover of 2.2e-08.
